Research Focus

Research in our group is focused on the use of synthetic organic chemistry and methodology to

  1. experimentally address questions concerning the origins of life with respect to the advent of functional monomers and the emergence of informational polymers.
  2. fashion artificial informational polymers in order to expand the interface between synthetic nucleic acids and the natural biopolymers (proteins and RNA/DNA).
  3. make available novel molecular tools that may provide new avenues for probing biological systems and for research in synthetic biology.
